2243-90-5 Usage
Uses
Used in Rubber Industry:
2,6,8-Trimethylquinoline is used as an antioxidant in the production of rubber products, particularly tires, to prevent oxidation and degradation caused by exposure to air and sunlight. Its ability to counteract the effects of oxygen and UV radiation enhances the durability and longevity of rubber products.
Used in Polyurethane Foam Production:
In the polyurethane foam industry, 2,6,8-trimethylquinoline serves as a stabilizer, ensuring the stability and quality of the foam during the manufacturing process. Its presence helps maintain the desired physical and chemical properties of the foam.
Used as a Reagent in Organic Synthesis:
2,6,8-Trimethylquinoline is also utilized as a reagent in organic synthesis, contributing to the formation of various chemical compounds and intermediates. Its unique structure and properties make it a valuable component in the synthesis of pharmaceuticals, dyes, and other specialty chemicals.
However, it is important to note that 2,6,8-trimethylquinoline has been classified as a Group 2B carcinogen by the International Agency for Research on Cancer, indicating that it is possibly carcinogenic to humans. Therefore, exposure to TMQ should be minimized to reduce potential health risks, and appropriate safety measures should be implemented in industries where it is used.
Check Digit Verification of cas no
The CAS Registry Mumber 2243-90-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,4 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2243-90:
(6*2)+(5*2)+(4*4)+(3*3)+(2*9)+(1*0)=65
65 % 10 = 5
So 2243-90-5 is a valid CAS Registry Number.

supporting information, p. 86 - 92 (2019/12/26)
The condensation of anilines and alkenyl ethers has been demonstrated by employing visible-light photoredox catalysis. The resulting method enables the synthesis of substituted 2-alkylquinolines under mild and simple conditions with good substrate scope and high yields.
Blue-light-promoted carbon-carbon double bond isomerization and its application in the syntheses of quinolines
Chen, Xinzheng,Qiu, Shuxian,Wang, Sasa,Wang, Huifei,Zhai, Hongbin
supporting information, p. 6349 - 6352 (2017/08/10)
A blue-light-promoted carbon-carbon double bond isomerization in the absence of any photoredox catalyst is reported. It provides rapid access to a series of quinolines in good to excellent yields under simple aerobic conditions. The protocol is direct, catalyst-free and operationally convenient.
